Is there any solution that doesn’t either involve developed countries lowering their quality of life or preventing developing nations from cheaply industrializing?
I seriously disagree with this framing. Developed countries have been artificially inflating their quality of life through cheap energy available from burning fossil fuels. This is an unsustainable practice that will a.) come to end due to exhaustion of said fuels b.) have significant, compounding externalities that are subject to incredible levels of reality distortion from entities benefiting from the economies they intentionally structured to be dependent on said energy sources.
The truth is that western countries have developed too fast through the planetary equivalent of roid rage. We've gone massively into debt, dug into a huge reservoir that is emptying, and the waste products produced by our flagrant exploitation of dirty energy reserves are very bad for the planet.
So yeah, I completely disagree with the "lowering their quality of life" framing. It's true that if you've been going into debt your whole life, and suddenly stop spending like a drunken sailor, your quality of life might go down.
What you’re saying isn’t wrong, but it is what it is. This is a political issue, acting as if switching entirely to renewables will not result in some short term sacrifices is well, disingenuous.
Trivially you could just ban those things. I think we’d agree in saying that would be very bad for many.
For example, what would be wrong with preventing developing nations from cheaply industrialising, while also subsidising them to do something else instead?
Subsidies are what we do now already which is why we’re in the situation we’re in.
Educating girls and empowering them on those countries also will make birth rates to decline faster.
